JOSEPH LA BRECHE VIGER, or MONTREAL, QUEBEC, CANADA.

MAGNETIC SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 278,976, dated June 5,1883.

Application filed December 4, 1882. (No model.)

To all whom, it may concern:

Be it known that I, J. LA BRECHE VIGER, of Montreal, in the Province ofQuebec and Dominion of Canada, have invented a new and Improved MagneticSeparator, of which the following is a full, clear, and exactdescription.

-My machine is intended to separate ironsand from common sand, theobject being to obtain as large a percentage as possible of the ore freefrom other sands.

The invention consists in an endless traveling apron combined withaseries of magnets placed at an inclination, so that as the sand is I fedto the side of the apron the magnetic particles will be retained thereonand carried forward to the discharge end, as hereinafter described andclaimed.

I Reference is to be had to the accompanying 2o drawings, forming a partof this specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 is a side elevation of my improved machine. Fig. 2 is an endview of the same.

Fig. 3 is a detail section of the feeding-hopper.

At the ends of an upright frame, A, of rectangular form, are fittedrollers B B, around which passes an endless apron, C, of cloth or othersuitable material, the apron also passing around a third roller, D,which is designed to be adjustable for tightening the apron. Behind theflat side of the apron is fitted aboard, E, that is formed with groovesor slots extend ing from one roller B to the other roller B at 3 5 anangle of about thirty-five degrees. In the slots or grooves of thisboard are magnets a, that may be either permanent or electro mag- Inets, and they are so placed that their poles are in contact, or nearlyso, with the inner sur- 0 face of the apron C. Upon the frame A is ahopper, F, provided in its lower portion with an endless apron, b,whichacts to carry the material and deliver it to tubes 61, that terminate onthe face of the apron in front of the magnets at the higher ends of theseries. One of the rollers B is fitted for operation by means of a belt,6, passing from a driving-pulley, f, and the pulley f is also connectedby a belt to a shaft, 9, that operates the feed-apron b.

In the operation of the machine, the material, being placed in thehopper F, is conveyed by the tubes (1 anddischarged against the face ofthe apron. The magnetic portions will adhere to the apron along the rowsof magnets, and thus be carried to the opposite end'of the apron, and atthe same time moved downward thereon by theinclination of the rows ofmagnets. The non-magnetic material will fall immediately, while themagnetic materials will be retained until they reachthe lower magnets,when they will fall in a separate pile. The frame A is fitted withsuitable supports for retaining it in an upright or more or lessinclined position.

Having thus described my invention, I claim as new and desire to secureby Letters Patent In magnetic separators,the upright or nearly uprightboard E, 'having the downwardly-inclined rows of magnets a, incombination with the endless moving apron 0, arranged in close 70contiguity with the poles of the magnets, and hopper F,having spouts d,feeding the material to the apron or carrier Q opposite to the upperends of the rows of magnets, substantially as and for the purpose setforth.
